回答“Won't turn on, but makes a beeping sound.”I unplugged EVERYTHING from the Xbox 360. Power, internet, all usb peripherals. Then plugged in ONLY power: Xbox came on like it should. I then went on adding 1 thing at a time to test each thing: powering the Xbox off, plugging in new item, powering it on, until everything worked fine. It is working like it was before.
